摘要:
目标跟踪的目标是利用位置数据实时估计目标的位置、速度和加速度。本文介绍了一种新颖的目标跟踪技术,该技术采用自适应输入与状态估计(AISE)进行实时数值微分,以根据位置数据估计速度、加速度和加加速度。这些估计值用于在Frenet-Serret(FS)坐标系内对目标运动进行建模。通过在SE(3)中表示该模型,利用不变扩展卡尔曼滤波(IEKF)估计位置和速度。所提出的方法称为FS-IEKF-AISE,通过数值示例进行说明,并与现有技术进行比较。
英文摘要:
The goal of target tracking is to estimate target position, velocity, and acceleration in real time using position data. This paper introduces a novel target-tracking technique that uses adaptive input and state estimation (AISE) for real-time numerical differentiation to estimate velocity, acceleration, and jerk from position data. These estimates are used to model the target motion within the Frenet-Serret (FS) frame. By representing the model in SE(3), the position and velocity are estimated using the invariant extended Kalman filter (IEKF). The proposed method, called FS-IEKF-AISE, is illustrated by numerical examples and compared to prior techniques.
